Her research focuses on understanding the psychology of cooperation within and between groups. In her research, she investigates predictors of group-bounded (parochial) and cross-group (universal) cooperation. Additionally, she investigates representative negotiations and how representative-constituency dynamics influence negotiation processes, agreement, and post-agreement approval. Although her research often takes an experimental approach, she is additionally interested in field research on understanding team conflicts and how to handle them (through appropriate conflict management, leadership and mediation). She has published in international top journals on these and related topics and has ongoing collaborations with colleagues in The Netherlands, Belgium, Germany, Denmark, Spain, Israel and the USA.
